EDWARD L. MEGILL, OF

NEW'YORK, N. Y.;'ALFREDI v. HART nxncuron on slur) EDWARD L. MEGILL, nncnnsnn,

PRINTING-PRESS GAUGE.

Application filed March 18, 1920. Serial No. 366,769.

To all whom it may concern I Be it known that I, EDWARD L. MEcILL, a citizen of the United States, residing at New York, in the county of New York;

and State of New York, have invented certain new and useful Improvements in Printing-Press Gauges, of which the following is a specification.

This invention relates to feed gauges of the type which are secured to the tympan.

sheet, and which are ordinarily known as gauge pins.

The objects of the invention are to provide a gauge pin of simple, inexpensive and durable construction and furtherto provide such a gauge'with a readily adjustable and automatically held gauge tongue.

A further object of the invention is to provide a gauge tongue especially adapted for guiding the edge portion of the sheet.

' Other objects and aims of the invention than those stated, together withqthenovel features of the invention will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations and arrangements of parts; and the broad scope of protection contemplated will appear from the claims. 1 V

In the accompanying drawing which is to be taken as a part of the specification and in which I have shown merely one preferred embodiment of the, invention, Figure 1 is a perspective view of three of the gauges as applied to a tympan sheet. Figure 2 is a top plan view of one of the end gauges.

Figure 3 is a longitudinal sectional View of the same on substantially the plane of line 3-3 of Figure 2.

Figure 4 is a bottom plan view of this gauge with a portion of the lower member or prong indicated as broken away and Fig-- 'ure 5 1s a plan- View of the blank from which the body of the gauge is made. I 1 Referring first to the blank froinwhich the gauge is made, it will be noted that the same consists of a sheet metal blank embodying a prong portion 7, a vertical head portion 8 anda plate portion 9. The head or gauge "face 8 has positioning points 10 projecting from oneedge thereof and this head is provided with aguide passage 11 therethrough, between the top and bottom edges thereof.

The plate portion 9 is provided with a similar guide passage 12 therethrough, in, line with the guide passage inthe head and dividing the rearward portion of the plate into separated arms13 connected at the rear by a cross bar 14. Projecting rearward from the central portion of this cross bar. and in line with the two guide passagesll and 12 is a tabl5 which in the final form of thedevice is curled toform a lip.

In forming up the device from the blank, the head part 8 is bent at right angles to. the plate portion 9 and the prong is bent under the plate portion so as to standsub! stantially parallelthereto, as indicated most clearly in Figure 3, to which view the reference characters heretofore used have been applied. The rearward portion of the top plate 9, that is the part involving the spaced arms 13,is bent under the top plate and directed toward the under side thereof. This provides a reverse bend 1.6 which 00- operates with the prong 7 to grip the tympan sheet 17, without possibility of tear ing or marring the latter.

This reversel bent portion also provides a spring clip for frictionally holding a gauge tongue 18 in position against the under side of the-top plate, said gauge tongue being adjustably guided in the alined passages 11 and 1-2 in the head and in the reversely bent portion of the top plate respectively. The end of this clip, as rep. resented by the tab 15, is bent outwardly, as shown in Figure 3, to form the lip previously referred to and which serves .to. frictionally grip the tongue at a single pointof contact and also provides an inclined surface enabling the end of the gauge tongue to-be readily inserted thereunder.

The device is applied to the tympan sheet in the usual way by inserting the prong beneath the sheet and permitting the point of the same to project up through the sheet at a point in rear of the reversely bent gripping portion ofthe top plate, the points at the head 10f the gauge beingdepressed extremely simple and practical, in that the entire body of the gauge is made 'in'but one piece, the reversely bent portion of the top plate being utilized both to serve as a means for gripping the top of the tympan sheet and also in respect of the cross bar 14 or tab 15 thereof as a spring clip for holding the gauge tongue against plate 9.

Where the device is used as an edge gauge for the sheet, as is the case at 20 in Figure 1, the lon itudinally adjustable gaugetongue is referably" formed or provided with angularly projecting extensionalprojeeting in but wholly above the planeot the paper feed. This extension materially assists in guiding the sheet past the face of the'gauge andalso aids in passingthe sheet in straight ened 'co1'1di'tion onto the end gauges 2% 23 for the lower edge of the sheet; I

It will be apparent that the device of this invention can-be inexpensively produced and that further while it is quite light in Weight,

it is of adurable construction andinay be easily handled and adjusted, and that,

" ther, it is well adapted to either machine or hand feeding. I claim 1. A gauge comprising a head portion provided with a passage therethrougl'i and a conneeted top ortion having its endpart the head, a gauge tongue-'slidingly enga ed in said assages and adjustably held by. the clip against the underside of'thetop and a member connected to theheadand' cooperatingwith the reversely bent part of the top to gripe tympa'n sheet;

2. A gauge comprising ahead portion provided With a passage therethiough and a eonnectec'l top portion having its endpart bent under and directed toward theunden side of the top portion" to provide" a clip,

said top portion having'a passage at the bend therein in line with the passage in the head, a gauge tongue sliding-1y engaged in said passages and adjustably h'e'ldby the clip against the underside of the top, said clip having a reversely bent lip facing the guide passage'in'the head, and a member connected to the head and cooperating with the reversely bent part of the "top to grip a t mpan sheet.

3. A gauge comprisinga head portion provided with a assage theretln'ouglr and a conne ted top portion having its end part bent under and directed toward the underside" of the top ortion to provide a clip, said top portion having a passage-at-the bend therein in linewith the'passage in the head, a gauge tongue 'slidingly engagedsaid passages and adjustably held by the clip against the underside of thetcp, and a member connected with the head and arranged 'to enter between the separated parts provided by the guide passage 1n the reverse bend of the top. p I r d. A gauge comprising a head portion provided with a passage therethrough and said assages and adjustably held by "the clip a ainst the underside of the top, said cllp lldjvlhg a revei-sely bent lip facing the uide passage in thehead, and a member connected with the head andarranged to enter between the separated part-s provided by the guide passa e in the reverse bend of the to 5.
